The Canon RF 15-30mm f/4.5-6.3 IS STM pairs a portable design with a flexible focal length range ideal for landscape, architecture, and street subjects. Complementing the ultra-wide to the wide range is also an Optical Image Stabilizer to reduce camera shake and a stepping AF motor that suits both photo and video uses. Covering ultra-wide to wide-angle fields of view, this lens spans a useful range of focal lengths for a variety of subject types, including landscape, architecture, interiors, and street applications. Modest variable maximum aperture contributes to a compact, lightweight design that's ideal for travel and walkaround shooting. Two UD (ultra-low dispersion) glass elements control a variety of chromatic aberrations for high clarity and color accuracy. One aspherical element reduces spherical aberrations and distortion for improved sharpness and accurate rendering. Super Spectra Coating minimizes flare and ghosting for greater contrast when working in strong lighting conditions. Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation. STM stepping motor offers fast, quiet, smooth, and accurate autofocus performance that is ideal for video recording as well as still shooting. Close-up focusing capabilities enable working with a 1:2 maximum magnification and a 5.1" minimum focusing distance to suit photographing nearby subjects.
